LADDER.

'Application filed August 25, 1924. Serial No. 733,861.

To all whom t may concernf 3e it known that I, NICHOLAS PELLIGREEN, acitizen of the United Stat-es, and resident of the city of St. Louis,and State of Missouri, have invented certain new and useful improvementsin Ladders, of which the following is a specification containing a full,clear, and exact description, reference being had to the accompanyingdrawings, forming a part thereof.

My invention relates to improvements in ladders and has for its primaryobject a ladder which is provided with a folding stand whereby the samemay be held in vertical position.

A further object is to construct a ladder provided with a folding stand,which stand is adjustable so that the ladder may be held vertically on'uneven surfaces making my device especially useful on sidewalks 'whichslope and also for fruit-pickers.

A still further object is to construct a ladder provided with a standfor supporting the same vertically, in which the stand ladder used inthe same manner as an ordinary ladder.

My improved ladder is .also used for paper hangers, painters and housecleaners as scaffold can be readily supported on the rungs of two spacedapart ladders thus i'tifording a platform for the workmen.

In the drawings:

Fig. 41 is a perspective view of my improved'ladder showing the samesupported in vertical position and illustrating the folding up of thelegs by dotted lines;

Fig. 2 is an enlarged section taken on the line 2-2 of Fig. 1; and

Fig. 3 is a horizontal iine 3-3 of Fig. 2.

In carrying out my device I employ a ladder having side members 4, thesemembers are spaced. apart as illustrated and have secured therein rungs5. The side members 4 are also provided with slots 6 and 7., the slots 6in both members 4 being opposite each other when the ladder isassembled, as are also the slots 7. The slots 6 and 7 extendlongitudinally of the members 4 and are also spaced apart and preferablyat. such a distance as rung to be inserted therebetween. Extendingthrough the slots 6 is a rod 8 which is screw threaded as at 9 so as toreceive a thumb nut 10. The opposite end of the rod 8 is provided with ahead. Surrounding the section taken on the to permit a rod S and locatedbetween the members 4 is a pipe 1.1, this pipe 11 is designed totalrethe place of one of the rounds or rungs of the ladder.

Pivotally supported on the rod Sere legs 12. these legs are spaced apartfrom the members 4 by means of a washer 13. On the outside of the legsv12 is placed a second washer 14 against which the thumb nut 10 and thehead, formed on the opposite ends of the rod S, bear respectively.Secured to the lower end of the legs 12 are chains 15, the opposite endsof the chains are each provided withA a hook 16 which is designed to besecured in an eye 17 carried by each of the members 4. In place of thehook 16, a snap fastener may be used, if found desirable. The purpose ofusing the snap fastener or hook 16 is to permit thechain to bedisengaged from the eye 17 so that the legs 12 ymay be folded upwardalong the members 4, as indicated by dotted lines in' Fig. 1, and thechains wrapped around the members 4 thus holding the legs 12 in foldedposition.

Passing through the slots 7 is a rod 18 which is constructed in the samemanner as the rod 8 and is provided withl the thumb nut and with washers13 and 14. The rod 18 extends through the legs 19 at a pointintermediate their ends, leaving projections 20 above the rod 18, theends of which are designed to contact with the edges of the legs 12thereby preventing any collapsing of the legs.

Secured to each of the eyes 17 is one end of a chain 21, the oppositeend of which is secured to one of the legs 19. The purpose of the chains1o and 21 is to permit the spreading of the legs and thus prevent anypossibility of the collapse of the ladder.

The setting up of my device is as follows The hook chains is firstfastened to the eyes 17, after which the legs 19 are pulled out.` asindicated in Fig. 1. and in so doing the ends 20 of the legs 19 contactwith the edges of the legs 12 forcing them out in the position shown inFig. 1. This position assures a vertical arrangement of the ladder withthe lower ends of the side members 4 resting on the ground. The thumbnuts 10 are then tightened up on the rods 8 and 18 thus securely holdingthe legs in extended position and preventing any collapse.

or securing means 16 of thel The slots 6 and 7 formed in each of theside members 4 permit a certain amount of vertical adjustment or" thelegs 12 and 19 on the same side of the ladder thereby permitting thesame to rest on an inclined surface, as for instance, a sidewalk whichnaturally slopes toward the street. In this event, however, it ispreferable to block up under the side members 4 so as to form a iirmsupport for the ladder while the same is being held in verticalposition. 7ere this blocking up not done, the side members l toward thestreet would not be supported on the ground at all but only by thefriction set up through the tightening of the thumb nuts 10.

The pipes 1l which surround the rods 8 and 18 prevent the side membersfrom being drawn inward due to the pressure set up when the thumb nut 10is tightened and also serve as rounds for the ladder.

lWhen it is desired to use my ladder in the ordinary manner, the legs 12are swung up into the position indicated by dotted lines in Fig. 1, andsecured in said position by means of the chains 15, then the upper endof the ladder can be leaned against the wall or other support.

The washers 13 prevent the legs 12 and l5) from contacting with the sidemembers thus allowing their ready pivoting and at the same timeeliminate friction between the legs and the side members. It is alsopossible to adjust the legs 12 and 19 on the same side 'of the ladderindependently of' each other, this is sometimes necessary especially onuneven ground due to the fact that one leg will have to be fitted into adepression in the ground or surface, and by this independent adjustmentgreat stability can be given the ladder and all possibility of rockingeliminated.

The legs 12 and 19 are preferably so secured to the side members 4t thattheir lower ends will pass the eye 17, this is especially desirable withthe legs 19 so that when the legs 12 are folded upward, either side ofthe upper end of the ladder can be rested against a support and the legs19 swung out of the way so that the bottom end of the ladder can rest onthe ground.

Having fully described my invention, what I claim is A ladder comprisinga pair of side members having rungs therebetween and having a pair ofspaced apart longitudinally eX- tending slots in each of said sidemembers, rods extending through said slots, a tube surrounding each ofsaid rods and located between the side members and adapted to serve as arung, a leg pivotally mountet on each end of' one of said rods andlocated adjacent one oit said side members, a second pair of legspivoted intermediate their ends to the remaining rod and locatedadjacent the outside of the respective side members, one end of each ofsaid last mentioned legs adapted to contact with an edge of the Firstmentioned legs for supporting the same, means carried by the rodswhereby said legs may be secured to said side members against movement,and flexible means for limiting the spreading` of said legs.

In testimony whereof, I have signed my name to this specification.

NICHOLAS PELLIGREEN.
